December 2024

State Key Laboratory of Mesoscience and Engineering, Institute of Process Engineering, Chinese Academy of Sciences, Beijing 100190, China.

The existence of interfacial nanobubbles on electrode surfaces is thought to block the active area, leading to a considerable decrease in the energy conversion efficiency. Gaining insight into how bubbles form on electrodes will be beneficial for designing effective electrochemical cells and enhancing the electrolytic efficiency. In this article, molecular dynamics (MD) simulations are employed to make a systematic comparison of behaviors of interfacial nanobubbles on both flat and rough electrode surfaces in electrochemistry.

Chronic hepatitis B (CHB) is a chronic inflammatory disease of the liver caused by infection with the hepatitis B virus (HBV), which in later stages can lead to the development of end-stage liver diseases such as cirrhosis and hepatocellular carcinoma in severe cases, jeopardizing long-term quality of life, with a poor prognosis, and placing a serious financial burden on many families around the world. The pathogenesis of the disease is complex and closely related to the immune function of the body, which has not yet been fully elucidated. The development of chronic hepatitis B is closely related to the involvement of various signaling pathways, such as JAK/STAT, PI3K/Akt, Toll-like receptor, NF-κB and MAPK signaling pathways.

Hypertension-induced myocardial remodelling encompasses both structural and functional changes in cardiac muscle tissue, such as myocardial hypertrophy, fibrosis, and inflammation. These alterations not only impair the systolic and diastolic functions of the heart but also elevate the risk of cardiovascular events and heart failure. One of the primary contributors to hypertensive cardiomyopathy (HTN-CM) is the over-activation of the renin-angiotensin-aldosterone system (RAAS), which subsequently induces myocardial remodeling.

Porous liquids (PLs) are a novel class of flowing liquid systems that possess accessible permanent porosity, exhibiting great prospects in gas capture and separation. Nevertheless, the further development of PLs lies in the facile synthesis and regulation of PLs with low viscosities. Herein, a novel strategy of preparing type I PLs with super-low viscosity is proposed through a simple one-step covalent linkage reaction using UiO-66-NH as the pore generator and monoglycidyl ether terminated polydimethylsiloxane (E-PDMS) as the sterically hindered solvent, respectively.

Systems, Power and Energy Research Division, James Watts School of Engineering, College of Science and Engineering, James Watt South, University of Glasgow, Glasgow G128QQ, UK.

The thermal properties of various corn stalk tissues (including stem, husk, ear, cob, and leaf), high-density polyethylene (HDPE), and their blends were investigated using thermogravimetric analysis under a nitrogen atmosphere. The results indicate that the thermal decomposition process of corn stalk tissue/HDPE mixtures is delayed with an increasing heating rate, regardless of the tissue type. Besides, the structural differences among various corn stalk tissues significantly influence their thermal behavior, product distribution, and co-pyrolysis kinetics with HDPE.
